The libmpeg2 package contains a library for decoding MPEG-2 and MPEG-1 video streams. The library is able to decode all MPEG streams that conform to certain restrictions: “constrained parameters” for MPEG-1, and “main profile” for MPEG-2. This is useful for programs and applications needing to decode MPEG-2 and MPEG-1 video streams.
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Install libmpeg2 by running the following commands:
sed -i 's/static const/static/' libmpeg2/idct_mmx.c && ./configure --prefix=/usr \ --enable-shared \ --disable-static && make
To test the results, issue: make
check. To perform a more comprehensive regression
test, see the file test/README
in the
source tree.
Now, as the root
user:
make install && install -v -m755 -d /usr/share/doc/libmpeg2-0.5.1 && install -v -m644 README doc/libmpeg2.txt \ /usr/share/doc/libmpeg2-0.5.1
sed -i ...: This sed fixes problems with recent GCC compilers.
